How can I save an inventory with ItemStack?

I know you guys are probably going to tell me to go google it but I don't understand anything with it. Could someone walk me through saving the custom inventory with ItemStack?

 

If you want to save the whole inventory than I would use the inventory object. For example if you want to make pistons as chests than you have to save the inventory as value with the location as the key to a hashmap.
Plese tell me what exactly you want to do so that I can help you much easier

I think what you are asking is how to save the inventory to a file?

for (ItemStack is : inventory.get contents())
{
// save the item stack here.
}

 

97WaterPolo Ice3ider4 I made a plugin that opens a custom inventory when someone opens their enderchest. Instead of having 3 rows it only has 1. You can put stuff in it and it will stay until the server restarts. Once the server restarts, the item(s) in there are gone. What I needa do is save the inventory somehow. Do I need to save the inventory to a file or what?

 

football70500 Have you thought about using the EnderChest for that? You can still store 1 row in that, but never open it. Just copy the items.

pseudocode:

for(int i = 0; i<9; i++){
enderchest.setItem(i, inventory.getItem(i));
}

 

football70500 Yep you have to save the inventory for all the players :s

 

BUT BUT BUT: I also have perms for 2 rows, 3 rows, 4 rows 5 rows and 6 rows

football70500 Save it to a seperate .yml file then, you WILL find how to do this with a little help of Google.

 

Why dont you use inventory serialization, its probably the most efficient way to store inventories to YAML configuration files. Take a look at this resource by Phil2812 http://forums.bukkit.org/threads/serialize-inventory-to-single-string-and-vice-versa.92094/

 

CMG Why is it so complicated just to save an inventory. Can't I just make a saveInventory method?

 

football70500 That's a really good way to save the inventory to a file and you only have to copy two functions It's a bit complicated but what the function basically does is it saves the id, the data, the durabillity, the amount and the enchantment to a string

 

@football70500
Don't use that ^^ it doesn't account for ItemMeta. (Or doesn't last time I checked)

Simply save the inventory to a yml. Saves everything; Enchants, Custom Name, Lore, etc..

Code:java

 
 
public void saveInventory(ItemStack[] inventory, ItemStack[] armor, UUID uuid) {
try {
YamlConfiguration c = new YamlConfiguration();
if (inventory != null)
c.set("inventory.inventory", inventory);
if (armor != null)
c.set("inventory.armor", armor);
c.save(new File(Paranoia.getInstance().getDataFolder() + "/data/", uuid + ".yml"));
} catch (IOException e) {
Bukkit.getServer().getConsoleSender().sendMessage("[MCCreed] Failed to save inventory due to error: " + e.getMessage());
}
}
 
@SuppressWarnings("unchecked")
public void openSavedInventory(Player opener, Player target) {
YamlConfiguration c = YamlConfiguration.loadConfiguration(new File(Paranoia.getInstance().getDataFolder() + "/data/", target.getUniqueId() + ".yml"));
ItemStack[] inventory = null;
ItemStack[] armor = null;
 
if (c.get("inventory.inventory") != null)
inventory = ((ArrayList<ItemStack>) c.get("inventory.inventory")).toArray(new ItemStack[0]);
if (c.get("inventory.armor") != null)
armor = ((ArrayList<ItemStack>) c.get("inventory.armor")).toArray(new ItemStack[0]);
 
Inventory cloudInventory = Bukkit.getServer().createInventory((InventoryHolder) target, 54, "[MCC] " + target.getName());
cloudInventory.setContents(inventory);
if (armor != null) {
for (ItemStack i : armor) {
if (i != null)
cloudInventory.addItem(i);
}
}
opener.openInventory(cloudInventory);
}
 

You'll have to integrate that code to work as you need it to.

 

As I am new to the whole YAML configuration, where it says c.save(newFile(etc... under the saveInventory method, what should I replace Paranoia in

Code:JAVA

Paranoia.getInstance().getDataFolder() + "/data/", uuid + ".yml")

with? Would it be my new file configuration?

 

Paranoia.getInstance() is an instance of plugin. So you would replace that with your plugin, aka Main class.

 

yeah... about that... I just used all one class because I totally forgot about the saving inventory in the first place.

}

This is what I have. I get an error at the Main.getInstance(): The method getInstance() is undefined for the type Main

 

getInstance() is a method in my Main class, if you're only using one class and that class extends JavaPlugin (I'd assume) replace the entire Paranoria.getInstance() with 'this'.

 

Okay now that I did that, how can I make it actually save the inventory? Would I use InventoryCloseEvent?

 

football70500
Yes

 

and I would just say on the inventory close do saveInventory();?

 

Just call the saveInventory() method from any method or "event". Like so..

Code:java

 
saveInventory(player.getInventory().getContents(), player.getInventory().getArmorContents(), player.getUniqueId());
 

 

Upon loading, I get an error: it says abnormal plugin type

Funfact: ItemStack implements ConfigurationSerializable. (which means that you can use .set(key, itemstack) and getItemStack(key)

 

I don't understand. How can I get this to work?

 

football70500 Just like you can call config.set("key", 1) to set "key" to 1 in the config, you can use it with ItemStacks. Furthermore, you can use config.getItemStack("key") to get the ItemStack you saved with "key"

 

I'm still not understanding.

 

<-

Oh, and please learn Java. If you don't understand fireblast709, you really need to learn...

 

football70500 No I am not going to spoonfeed you code. Have a link that explains configurations.

 

I'm not asking you to 'spoonfeed' me code. I am confused as to how this would save everything in the custom inventory. It just doesn't make any sense that this would save the entire inventory.

 

football70500 I told you how you can save a single ItemStack. If you still don't get how you can save the inventory, I suggest you go check the javadocs .
